Imaging tool lets scientists look inside brain at nanoscale resolution

By - August 1, 2015 5 Pictures

The human brain contains more synapses than there are galaxies in the observable universe (to put a number on it, there are perhaps 100 trillion synapses versus 100 billion galaxies), and now scientists can see them all – individually. A new imaging tool promises to open the door to all sorts of new insights about the brain and how it works. The tool can generate images at a nanoscale resolution, which is small enough to see all cellular objects and many of their sub-cellular components (so for the biology-literate, that's stuff like neurons and the synapses that permit them to fire, plus axons, dendrites, glia, mitochondria, blood vessel cells, and so on).

Inexpensive new depth-sensing camera could outperform the Kinect

By - April 27, 2015 1 Picture
Although the Microsoft Kinect was designed first and foremost for gaming, the fact that it's a cheap but reliable depth-sensing camera has led to its use in everything from navigation systems for the blind to user-following grocery carts to remote-control cyborg cockroaches. Soon, however, it may be facing some competition. The Northwestern University-designed Motion Contrast 3D Scanning (MC3D) camera should also be economical, while offering higher-quality imaging and the ability to operate in sunlight. Read More

ESA's Sentinel-2A satellite arrives in French Guiana ahead of launch

By - April 27, 2015 2 Pictures
ESA's Sentinel-2A satellite has arrived safely in French Guiana, ahead of its June 12 launch atop a Vega rocket. It was carried in the belly of an enormous Russian-made Antonov cargo plane, and protected within a specially-constructed air conditioned habitat. Once operational, the satellite will represent a cornerstone of the agency's Copernicus program, which is striving to revolutionize how we observe and understand our environment, and how we may be able to tackle the detrimental effects of climate change.

"Google Maps for the Body" zooms in from whole organs down to individual cells

By - April 15, 2015 3 Pictures
The algorithms used for zooming in and out on Google Maps and Google Street View have made it possible to visually traverse through layers of the body – starting with a whole joint and drilling all the way down to the cellular level. The new imaging system could have huge implications in medicine because it drastically reduces the time required to analyze and compare data. Read More

New chip could turn phone cameras into high-res 3D scanners

By - April 7, 2015 2 Pictures
As if smartphones can't already do enough, soon they may be able to scan three-dimensional objects and send the resultant high-resolution 3D images to a 3D printer that produces hyper-accurate replicas. This comes thanks to a small and inexpensive device called a nanophotonic coherent imager (NCI), which was developed by scientists at Caltech. The NCI could add 3D imaging to a variety of other devices and applications such as improving motion sensitivity in human machine interfaces and driverless cars. Read More

MRI-based cancer detection technique could replace biopsies

By - March 30, 2015 2 Pictures
While non-invasive imaging technologies, such as mammograms or CT scans, are capable of detecting tumors, identifying whether they are malignant or benign usually involves getting out the scalpel and conducting a biopsy. Now researchers at Johns Hopkins University have developed a technique that uses magnetic resonance imaging (MRI) to noninvasively detect cancerous cells, offering the potential of supplementing biopsies or maybe one day replacing them altogether.

Combination radio/radar imaging produces stunning view of Venus

By - March 16, 2015 2 Pictures
A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time. Read More
